By using an acousto-optic tunable hyperspectral imaging spectrometer as measurement equipment and a halogen as the target, a short-range experimental program was designed to verify the passive ranging technology based on oxygen absorption. The basic principles and experimental program of the passive ranging technology based on oxygen absorption were introduced. Then, experimental equipment and a target were chosen based on ranging principles and assumptions, and the passive ranging technology was tested and verified under short-range conditions. Experimental results proof that this passive ranging technology also has the ranging capability when the target radiation and atmospheric conditions are unknown, which shows the feasibility and advantages of this ranging technology. The measuring range is solved by a software simulation curve and a model fitting curve, and the results give that the 4.26% ranging error comes from the model fitting curve and 6.23% ranging error from the software simulation curves. This result demonstrates that the model fitting curve based on experimental data not only can invert the target range in higher accuracy, but also can solve the measuring range of a far-range target by the curve extrapolation.
